Besides modafinil, which medication is commonly used to treat narcolepsy?

• A. Methylphenidate
• B. Diazepam
• C. Acetaminophen
• D. Gabapentin

Answer: (A)

The main idea here is how narcolepsy is managed to improve daytime wakefulness. Methylphenidate is a CNS stimulant that increases dopamine and norepinephrine activity in the brain, which boosts alertness and helps reduce excessive daytime sleepiness. Because modafinil and methylphenidate both promote wakefulness, methylphenidate is a common alternative or add-on therapy for narcolepsy.

Diazepam would tend to worsen daytime sleepiness and isn’t used to treat narcolepsy. Acetaminophen is simply a pain reliever with no effect on wakefulness, and gabapentin is an anticonvulsant/neuropathic pain drug not used to promote wakefulness in narcolepsy.
